Checkpatch flags CamelCase identifiers in strict mode, but it has a
feature to ignore parts with only two characters to allow for SI units
like mV or uA. Unfortunately, not all SI units fit in two characters, and
not all are lower case followed by upper case.
This patch adds hardcoded detection for frequency and 1024-based size
units (Hz/KHz/MHz/GHz/THz and KiB/MiB/GiB/TiB), since allowing any three
character combinations might be too lenient. The list can later be

c90 section "6.7.2 Type Specifiers" says:
"type specifiers may occur in any order"
That means that:
short int is the same as int short
unsigned short int is the same as int unsigned short
etc...
checkpatch currently parses only a subset of these allowed types.
For instance: "unsigned short" and "signed short" are found by
checkpatch as a specific type, but none of the or "int short" or "int
signed short" variants are found.
Add another table for the "kernel style misordered" variants.
Add this misordered table to the findable types.
Warn when the misordered style is used.

Using an else following a break or return can unnecessarily indent code
blocks.
ie:
for (i = 0; i < 100; i++) {
int foo = bar();
if (foo < 1)
break;
else
usleep(1);
}
is generally better written as:
for (i = 0; i < 100; i++) {
int foo = bar();
if (foo < 1)
break;
usleep(1);
}

Logging messages that show some type of "out of memory" error are
generally unnecessary as there is a generic message and a stack dump
done by the memory subsystem.
These messages generally increase kernel size without much added value.
Emit a warning on these types of messages.
This test looks for any inserted message function, then looks at the
previous line for an "if (!foo)" or "if (foo == NULL)" test and then
looks at the preceding statement for an allocation function like "foo =
kmalloc()"
ie: this code matches:
foo = kmalloc();
if (foo == NULL) {
printk("Out of memory\n");
return -ENOMEM;
}
This test is very crude and incomplete.
This test can miss quite a lot of of OOM messages that do not have this
specific form.
ie: this code does not match:
foo = kmalloc();
if (!foo) {
rtn = -ENOMEM;
printk("Out of memory!\n");
goto out;
}
This test could also be a false positive when the logging message itself
does not specify anything about memory, but I did not find any false
positives in my limited testing.
spatch could be a better solution but correctness seems non-trivial for
that tool too.

A commit hook for the Gerrit code review server [1] inserts change
identifiers so Gerrit can track patches through multiple revisions.
These identifiers are noise in the context of the upstream kernel.
(Many Gerrit servers are private. Even given a public instance, given
only a Change-Id, one must guess which server a change was tracked on.
Patches submitted to the Linux kernel mailing lists should be able to
stand on their own. If it's truly useful to reference code review on a
Gerrit server, a URL is a much clearer way to do so.) Thus, issue an
error when a Change-Id line is encountered before the Signed-off-by.

This test is a bit noisy and opinions seem to agree that it should not
warn in a lot more situations.
It seems people agree that:
return (foo || bar);
and
return foo || bar;
are both acceptable style and checkpatch should be silent about them.
For now, it warns on parentheses around a simple constant or a single
function or a ternary.
return (foo);
return (foo(bar));
return (foo ? bar : baz);
The last ternary test may be quieted in the future.

This change restricts the check for the for the FSF address in the GPL

So for example this statement will still return an error:
